Do you still remember the time when you had to dismount the stores in order to check it's integrity, and running "Isinteg -S "servername" -Fix -Test AllTests" at a regular command line, once or twice, depending on the errors/ warnings ???
Well, those days are gone :)
In Exchange 2010 SP1, ISInteg is no longer a standalone program.
The functionality provided by the ISInteg tool has been rolled into two new Exchange Management Shell cmdlets:
How does it do that? Well, the new schema in Exchange 2010 effectively partitions the database by mailbox. So the top problems fixed by ISInteg are now mostly limited to the affected mailboxes only. Previous versions of ISInteg required the database to be offline while validation and fixing are in progress. In Exchange 2010 SP1, the ability to do these checks at the mailbox level removes the need to dismount the database. It is actually required to have ISInteg operate against an online database!
New-MailboxRepairRequest -Mailbox <MailboxIdParameter> -CorruptionType <MailboxStoreCorruptionType> [-Archive <SwitchParameter>] [-Confirm [<SwitchParameter>]] [-DetectOnly <SwitchParameter>] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]
New-MailboxRepairRequest -Database <DatabaseIdParameter> -CorruptionType <MailboxStoreCorruptionType> [-Confirm [<SwitchParameter>]] [-DetectOnly <SwitchParameter>] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]
You can run a repair task with multiple parameters if you separate them with a comma (as shown in the Examples section below).
The New-PublicFolderDatabaseRepairRequest cmdlet detects and fixes Public Folder replication state problems.
New-PublicFolderDatabaseRepairRequest -Database <DatabaseIdParameter> -CorruptionType <PublicFolderDatabaseCorruptionType> [-Confirm [<SwitchParameter>]] [-DetectOnly <SwitchParameter>] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]
New-MailboxRepairRequest -Mailbox firstname.lastname@example.org -CorruptionType SearchFolder, AggregateCounts, ProvisionedFolder, FolderView
New-MailboxRepairRequest -Mailbox administrator -CorruptionType SearchFolder, AggregateCounts, ProvisionedFolder, FolderView -WhatIf
New-PublicFolderDatabaseRepairRequest -Database PFD01 -CorruptionType ReplState -DetectOnly
Some additional examples are provided in the cmdlet help. You can retrieve them using the following commands, or refer to New-MailboxRepairRequest and New-PublicFolderDatabaseRepairRequest cmdlet reference:
Get-help New-MailboxRepairRequest -examples Get-help New-PublicFolderDatabaseRepairRequest -examples
I recommend that you get to know the cmdlets by using the cmdlet reference docs, or by using the following commands to retrieve detailed help from the shell:
Get-help New-MailboxRepairRequest -detailed (or -full) Get-help New-PublicFolderDatabaseRepairRequest -detailed (or -full)
There are, obviously, some things to remember :
